Collect on IdentitySet

by Jan KurÅ¡

Hey All, The collect: on IdentitySet returns Set. Is this really wanted behaviour or is it a bug? For example: set := IdentitySet with: 'foo' with: 'bar'. newSet := set collect: [:e | #size -> e size ]. This two assertions do not pass: self assert: newSet size == 2. self assert: newSet class == IdentitySet Surprisingly (for me), if I change the implementation of collect: to use self species new instead of: Set new, the Pharo becomes really unresponsive... Cheers, Jan

Re: [Pharo-dev] Is Metacello in Pharo 5.0 up-to-date? and project locking

by Peter UhnÃ¡k

Hmm, #onWarningLog doesn't exist either. I'm assuming this is the issue https://pharo.fogbugz.com/f/cases/15456/Load-latest-version-of-metacello There's linked github issue https://github.com/dalehenrich/metacello-work/issues/354 But running the script (in the github issue) fails, because there's no defined spec for FileTree for Pharo 5.0 I'm not knowledgeable in Monticello so I don't know if I can do anything to help besides user testing.

No. There is an issue on the issue tracker. If nobody pushes, nothing will happen.

Re: [Pharo-dev] Is Metacello in Pharo 5.0 up-to-date? and project locking

by Dale Henrichs

Peter, I don't know what version of Metacello is loaded into Pharo4.0, but if you are using the latest version of Metacello, locks are honored by default and no onConflict: block is needed ... as an aside, there is #onWarningLog, so you can do something like: Metacello new baseline: 'ProjectBBB'; repository: 'gitfiletree:///projectBBB'; onWarningLog; load. to both honor locks and log Warnings to the transcript ... if you want to filter known warnings, then you can use #onWarning: ...

Is Metacello in Pharo 5.0 up-to-date? and project locking

by Peter UhnÃ¡k

Hi, I was playing around with metacello because I wanted to ignore warnings with locks... currently I am doing something like ~~~~~~~~ Metacello new baseline: 'ProjectAAA'; repository: 'gitfiletree:///path/to/projectAAA'; lock. Metacello new baseline: 'ProjectBBB'; repository: 'gitfiletree:///projectBBB'; onConflict: [ :ex | ex allow ]; load. ~~~~~~~~~ This will load both projects via gitfiletree, however it will also generate a lots of lock warnings which I have to manually confirm - this is bad for scripts. So the docs ( https://github.com/dalehenrich/metacello-work/blob/master/docs/LockCommandR… ) mention onLock: [ :ex | ex honor ], however in Pharo 5.0 there is no such method "honor". Is this bug? Should Metacello be updated on Pharo 5.0? Will this even solve my problems? (Honoring locks while not throwing warnings). Thanks, Peter

Off Topic: Children 3-13yr english program -- 4 weeks free access

by Ben Coman

greetings all, This is a long way off topic, but a random chance someone in the community with kids learning english may find it useful. The past year I've had m y4 & 6yr old girls doing Reading Eggs. Its aimed at native-english children ages 3-13 (starting with a test to place kids at a stimulating level). Its been beneficial for my kids, so I'm forwarding this offer to the community. http://e01.ams11.com/OutboundMessage.aspx?M=1581.347AD7EE-9C8B-4665-A061-90… cheers -ben
